I am in fact doing asteroid occultations, yes! Thanks for sharing what you did, I will see if it applies.
I saw from the QHYCCD SDK documentation that "the camera records the GPS information and insert into each frame's head." So it would seem that the images the camera sends to INDI contains the exact GPS timing, but INDI then overwrites it (or simply ignores it) in favor of the PC timestamp. If I understand correctly, when INDI saves the images, the GPS timing isn't saved with it because the header is changed to INDI's. So I don't think I could read the original timestamp on the image ://

I am not all that familiar with C++, unfortunately so I can't be trusted with modifying the StreamManager class.. If anyone were to look into it I'd be super grateful.
